General Description
●The LM2621 is a high efficiency, step-up DC-DC switching regulator for battery-powered and low input voltage systems. It accepts an input voltage between 1.2V and 14V and converts it into a regulated output voltage. The output voltage can be adjusted between 1.24V and 14V. It has an internal 0.17ΩN-Channel MOSFET power switch. Efficiencies up to 90% are achievable using the LM2621.
